JP2001228961A - Method for encoding latin character - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enhance the efficiency of inputting Latin characters by reducing the frequencies of key depression when the number of keys are restricted. SOLUTION: The Latin characters are first divided into strokes. Next, the strokes are divided into eight sets, codes are defined for every set and imparted to the eight keys. One remaining key is reserved for the space and another key is reserved for switching among accents, tremors and peculiar characters of different languages.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of encoding Latin characters by a combination of ten keys for inputting Latin characters to an information device having a limited number of keys.

[0002]

2. Description of the Related Art Conventionally, in an information device in which the number of available keys is limited, several Latin characters are assigned to the same key and divided according to the number of times the key is pressed (FIGS. 1 and 2).

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to reduce the number of key presses when the number of keys is limited, and to increase the efficiency of inputting Latin characters.

[0004]

SUMMARY OF THE INVENTION To achieve the above goals, the present invention first classifies Latin characters into brushes. Next, the brush is divided into eight sets, codes are defined for each set, and the codes are assigned to eight keys. One other key is provided for the space, and the other key is used for switching to accents, trema, and language-specific characters.

[0005]

DETAILED DESCRIPTION OF THE INVENTION In FIG. 3, a Latin character brush is defined.

In FIG. 4, a brush composition for each Latin character is defined.

[0007] In Fig. 5, a brush configuration for each set and its codes B1 to B8 are defined. In addition, a space code B0 and a code B9 for switching between accents, trema, and special characters are also defined.

In FIG. 6, a brush-set code for each Latin character is defined.

In FIG. 7, B0 to B9 are distributed to ten keys without any relation in order.

[0010]

8 and 9 show one embodiment of the present invention directed to Spanish.

[0011]

According to the present invention, it is possible to input Latin characters only by pressing the key about 1.9 times on average.
